Summary

At present the standard management of fluid overload in patients with congestive heart failure (CHF) involves limiting the intake of salt and water while administering high dose diuretics, often at the cost of deteriorating kidney function. However, another group of researchers has previously shown that intravenously infusing small volumes of concentrated saline during diuretic dosing and liberalizing dietary salt intake while continuing to limit water consumption resulted in improved fluid removal in CHF patients. Furthermore, less deterioration in kidney function, shorter hospitalizations, reduced readmission rates, and even reduced mortality were observed. The present study will examine this novel therapy in a population of 60 patients with underlying severe CHF and kidney dysfunction hospitalized for the management of fluid overload. Half of these patients will receive investigational treatment with concentrated salt infusions and liberalized salt consumption during diuretic therapy. All patients will otherwise receive the standard therapies for heart failure, including restrictions on water consumption. This study will attempt to verify the improvements in clinical endpoints previously described and define the mechanisms of enhanced fluid removal.

Conditions

• Congestive Heart Failure
• Renal Insufficiency

Interventions

Type	Name	Description
DRUG	Hypertonic saline, then oral sodium chloride	2mL/kg hypertonic saline (4.4% NaCl if serum sodium \</=135, else 2.8% NaCl) infused over 30min BID and dosed simultaneously with IV bolus furosemide BID (latter dose per treating physician) until patient is switched to oral loop diuretic. After switch to oral diuretic, subject will receive oral 0.75gm sodium (NaCL) capsule dosed BID with loop diuretic (latter dose per treating physician) until 60d after discharge.
DRUG	Normal saline, then oral placebo capsule	20mL normal saline infusion X 30min BID dosed simultaneously with IV bolus furosemide BID (latter dose per treating physician) PLUS 2gm sodium diet PLUS 1.5L fluid restriction. After switch to oral diuretic, begin oral placebo capsule BID, dosed with loop diuretic (dose per treating physician) PLUS 2gm sodium diet PLUS 1.5L fluid restriction.
